My schools stalls for the girls, they are pretty clean. Besides the doors and walls that have graffiti, mainly how they dislike the new choir teacher, or the vice princaple. The sinks are okay, besides the empty boxes of female necessities...The walls are clean, no writing on them or any human solids....Trying to keep this as clean as possible. And I am not sure about the boys, but from what I hear from my friends that they are pretty immature brats when it comes to clean bathrooms.
